I know there is pilot domicile info on this website but I think it is largely outdated. Also, there is a map on another website but again that is also largely outdated as well.
I'm going to attempt to keep one current. Have a look at
www.pilotdomiciles.com
and let me know what you think. I know there are some inaccuracies on this map and I'm probably missing an airline or two but if you are a pilot for one of these airlines, post any updates/corrections and I'll make the changes.
